intake won't really do too much besides sound and easier RPM climb, and maybe a bit more low end torque. but this is still noticeable.
actual hp gains are prob somewhere between 3-6 hp from an intake, although some claim 10 hp like the injen, but i don't remember if this is actual, and i have heard that there is also some loss at a certain RPM.
( i have bmw perf intake FWIW. )
and this MOD would 100% NOT be affected by different intakes or exhausts, except for perhaps helping in power gains. so there won't be any problems springing up from varying set-ups.
